The handle 16, which consists of a shell 29 i and a'cover 31 carries thetwin needle at one end-of the shell and has its largest di mensionmidway between its two ends-and tapers from the middle towards bothends, a

socket member30 gripping the twin needle 15 atone end thereof. At theopposite end a cover 31 1s hinged'as at'32s0' as to swing in alongitudinal plane of the handle. In other words, it folds like a bladein a jackknife along line 33. The cover 31 and the cide so as to form asmooth joint. -Between the shell 29 and the cover 31 is formed shell 29join along a line 33 at one side of the handle where their outersurfaces coinahollow or chamber 34 which opens out wardly along one sideof the handle as at 3'5 and'also at the needle end of the handle as at36. A clasp 3'T'is' providedfor securing the cover 31 tothe shell 29when the "cover is foldedin closed position.

V- In the hollow or chamber 34 of the handle is deposited the case 17which is approximately pear shaped and fits loosely in the chamber, infact itis so loose that it will i rattle in the handle and permit athread to Theiuse of the tool is as follows --After pass over and aroundit. It terminates with a sharp point 38 which is intended toproneedle'end'of thehandle as seen in "Figures 1-, 2 and'3. The case isrecessed as at 39 to receive the bobbin 18'and a central stem '40 isprovided in the; recessand around which the bobbin 18 may revolve. Thecentral part-of the lid 41 has a thin shank'42 in its center and whichis threaded to engage with correspondingthreads 43 at the end-of thestem 40. Thislid41 is intended to retain the bobbin in position. Fromthe recess 39 a narrow slit 44 is' provided in the case 1-7 running fromthe recess 39 to a notch 45" near the edge of the case 17 Inthis notch1s seate'd'a tensioning spring 46 secured by means: of ascrew 47 or inany other suitable manner so as to make the'tensioning spring 4tiad1ustable over a thread passing from the bobbin through slit 44 andbetween the straight and folded fingers 48 and 49 respectlvely'of thetensioning' spring.

' the work 50 has been secured on a suitable work bench and a spool 51revolubly mounte'd adjacent to the work on the bench, theoperator-grasps the handle in one hand with the twin needle 15 pointingin the direction .7 of the work. For the first stitch the awl or prong23 is ppshed through the layers of the leather piercing it and afterthis has been done,the long prong 24 is pushed through v the 11016provided, while simultaneously the 1 short prong 23 againpierc'es theleather to provide-the'next hole. When the=long prong 24'has been pushedthrough'the work, its

hook 14 engages around the upper thread52 onthe-spool' 51 whereupon thetoolis retracted,when the hook on the prong-24 will I draw the upperthread through the'work as seen in Figure 1 forming a loop on thethread. hAnother thread 53, which is wound around its spool 18 depositedin the casing 17 within'thehandle '16, has its end secured in the workand as a long loopabout six 01? 7 aperture 55 previously producedby the7 V short prong 23,;which will-then produce'the hole for the nextstitch.

The nnderthread 53 from the'bobbin 18- when passing through the slit 44is suitably te nsionedby meanslof spring device 46 and thereupon made topass through the long- 9'0 opening'35 in theihandle to the under side ofthe work.

Having thus described the invention-what is claimed as new is:

'1. A handle for a needle, said handle g6 inga chamber with apermanently open slit along one side and one end thereof for admittinpi' looped thread, and'a bobbin de posited loosely in said chamberandcarrying a second thread adapted to run 7 out through said slit andto dock with said looped thread when the latter passes over said bobbin.Y 7 r r 2. Ahandle for a needle, said handle com prising a shell, acoverfor said shell, thecoverand the shell forming a chamber between oneside and one end of'said handle for ad} mitting a looped thread,:'andabobbinde- V positedloosely in said chamber and carrying a threadadapted V to' run out through said slit and to lock with saidlooped-thread when the latterpasses over said bobbin; 1 V

1 them with -a' permanently open slit: along r i lubly securing thebobbin therein, said bob admitting a looped thread, and a case fittingloosely within said chamber and having a pointed end adapted to protrudethrough theslit at said end in order to pass through a looped threadadmitted through said slit, said case forming a receptacle for a bobbincarrying a second thread adapted to pass through said slit and to lockwith said looped thread.

5. A handle for a sewing needle, said handle comprising a shell, a coverfor said shell, the cover and the shell forming a V chamber between themwith a permanently open slit along one side and one end of said handlefor admitting a looped thread, a case fitting loosely within saidchamber and having a pointed end adapted to protrude through the slit atsaid end in order to pass through a looped thread admitted through saidslit, said case having a recess, a bobbin carried in said recess, andmeans for revobin carrying a second thread adapted to pass through saidslit and to look with said looped thread.

6. A handle for a sewingneedle, said handle comprising a shell, a coverfor said shell, the cover and the shell forming a chamber between themwith a permanently open slit along one side and one end of said handlefor admitting a looped thread, a case fitting loosely within saidchamber and having a pointedend adapted to protrude through the slit atsaid end in order to pass through a looped thread admitted through saidslit, said case having a recess, a bobbin carried in said recess, and anopen ing being provided in the side of the case communicating with saidrecess and permitting a thread carried by the bobbin to pass throughsaid opening and said slit and to lock with a loop of another threadpassing around said case when admitted through said slit.

7. A handle for a sewing needle, said handle comprising a shell, a coverfor said shell, the cover and the shell forming a chamber between themwith a permanently open slit along one side and one end of said handleforadmitting a looped thread, a case fitting loosely within said chamberand having a pointed end adapted to protrude through the slit at saidend in order to pass through a looped thread admittedthrough said slit,said case having a recess, a bobbin carried in said recess, an openingbeing provided in the side of the case communicating with said recessand permitting a thread carried by the bobbin to pass through saidopening and said slit and to lock with a loop of another thread passingaround said case when admitted through said slit, and means adjacentsaid opening for tensioning said thread.

In testimony whereof I affix my signature.
